Looks like it's James Cusack covering Sam & Danni this afternoon, thumbnail for the afternoon shows his picture. https://www.bbc.co.uk/programmes/m002rrgk

Are they doing two shows then or someone else doing it 

Today - apparently Greg’s dad not well (they said at 7 when they came on, said they got the call last second last night).

When  

Sam & Danni sit in for Greg James

I wonder who Scott's main cover will be this year as well? I enjoyed hearing Mark Goodier over Christmas, and although it was slightly stripped back to Scott's usual show.. the 3rd week he did into January was a full blown breakfast show with Scott's features and guests which i think he handled quite well. I know they started using Sara Cox for breakfast cover, but with the amount of times she's was off with her own holiday and other projects.. she ended up spending a fair bit of time off teatime, which isn't ideal. Mark covering isn't as disruptive to the schedule.

I agree. I was under the impression he would cover all of OJ's holiday and when he's on daytimes, but Connor (who has his own weekday show on BBC Radio Ulster, and does regular cover on 5live) seems to do the majority now. On the subject of OJ, I wouldn't wish to lose Sara Cox, but he's really good when he sits in at teatime. He makes the show his own with his own features (a few of them exclusive to when he covers teatime), so i was glad when he started covering again recently as he had fell out of favour a bit first to Ellie Taylor, then Spoony. I wonder if Ellie Taylor will pop up again? I noticed she was present in the pictures from the presenter gathering they had not long back, despite the fact she hadn't been used for any cover in a while.   

It’s a shame that Phil Williams seems to have fallen out of favour, first losing his slot to Richie and now not seeming to be primary cover. I MUCH preferred his Monday morning slot to Richie now and I think he’s a very decent listen covering for OJ

Good Friday: Connor Phillips in for OJ Borg on overnights... ..as OJ is in for Scott on breakfast Gary Davies is in for Vernon    

Maia Beth is doing Future Pop in April for 3 of the 4 weeks. 29th March CassKidd in for Sian on the Chillest Show.

I would Imagine Dean will be in for Greg all week as they never updated the R1 Breakfast Show Description when Dean was on last Friday It will also be interesting if there is no Bank Holiday Weekend Special Schedule as there has been for a good few years

Mylo and Rosie in for Dean w/c 30th March. Dean’s listed for breakfast on Friday only, unclear if that’s just for that day or the whole week. That is Good Friday and the schedule is normal at the moment.

Sam & Danni in for Matt & Mollie tomorrow.

Saturday 14th and Sunday 15th March is C2C Music Festival with Bob Harris in place of Rylan's show, and Sounds Of The 70s.

16th March Emil Franchi in for Dean
